Landcover classification is a description of the type of vegetation growing in an area. Different types of plants (e.g., grasses versus pine trees) reflect uniquely, giving a 'spectral signature'. Scientists use satellites to detect the spectral signature of vegetation and produce landcover classification maps from the data. Landcover classification data has applications in urban planning, natural resources management, wildlife biology, and forestry.
